| + | Since I didn't have my bicycle in Bucharest, the only way to test this was to move the wooden mount with the system attached with my hand violently so that its acceleration surpasses the threshold acceleration. And it did work! I got the notification in the Serial Bluetooth Terminal app on my phone. | ||

| + | Looking at future improvements of this project, I would like to have the Bluetooth notification be able to trigger the Emergency SOS feature from Android. | ||
